• Thread size: M10 x 1, max engagement 15 mm

Environmental & physical ratings

• Temperature range (standard probe): –52°C to +177°C (–62°F to +350°F). Extended‑range tip up to +218°C, cable up to +260°C. Avoid below –34°C for pressure‑seal life.
• Humidity resistance: less than 3% ASF change after 56 days at 93% RH (IEC 68‑2‑3)
• Pressure seal: Viton® O‑ring seals differential pressure; not factory‑tested (custom test available)
• Weight: 323 g/m (11.4 oz/ft)

Frequently asked questions (FAQ)

• Q: Can I use this 5 m probe with a 7 m Proximitor? A: No. Bently Nevada designs the 5‑meter probe exclusively for the 5‑meter Proximitor sensor. Using mismatched lengths will cause inaccurate readings.
• Q: What is the exact linear range start? A: Linear range begins at 0.25 mm (10 mils) from the target and extends to 2.3 mm (90 mils). The recommended static gap is 1.27 mm (50 mils).
• Q: Does the probe work in high‑humidity areas? A: Yes. It passes 56‑day 93% humidity testing with less than 3% average scale factor change. The tip and case materials resist corrosion.
• Q: Can I mount this in a Class I, Zone 0 area? A: Yes, when you install it with approved intrinsic safety barriers (per drawing 141092) the 330103-00-03-50-02-05 qualifies for Zone 0.
